Abstract

VáLVULA, ELEMENTO DE VáLVULA E MéTODO DE OPERAR UMA VáLVULA. é apresentada uma válvula de controle do tipo de esfera com faculdades de fechamento bidirecional. A válvula (30) compreendendo uma entrada (31) e uma saída (32), um elemento de esfera (80) e um conjunto de vedação. Ao fechar a válvula, o elemento de esfera que é excentricamente montado sobre uma haste (90, 91), gira para confmar com o conjunto de vedação (50). Enquanto fechada, o conjunto de vedação incluindo um alojamento de vedação (52), uma vedação principal (64) e um membro resiliente, contata o elemento de esfera na vedação principal, enquanto o membro resiliente (70) compele a vedação principal no sentido do elemento de esfera. O conjunto de vedação adicionalmente inclui um trajeto de fluxo secundário (72) entre a vedação principal e o alojamento de vedação, que é restrito por uma vedação de alta temperatura.
